Definitions

  • the invention relates to a valve, in particular an electromagnetic valve according to the preamble of claim 1.
  • valve housing of which is fastened in a sealed manner in a stepped bore of the valve receiving body.
  • the valve housing is fastened in the stepped bore of the valve receiving body by means of two recesses which run around the circumference of the valve housing and into which the material volume of the valve receiving body is displaced during the pressing-in process.
  • FIG. 1 shows, by way of example, a cross section through a valve which is electromagnetically open in the basic position with the inventive fastening of the valve housing 1 in the valve receiving body 2 in a considerably enlarged illustration.
  • the valve housing 1 is an essentially sleeve-shaped part that is only a few millimeters in size, which preferably consists of a cold-drawn and a harder material structure relative to the valve receiving body 2.
  • the valve receptacle body 2 which is preferably made of an aluminum alloy, is accordingly less hard than the valve housing 1 made, for example, of free-cutting steel. This difference in hardness is ultimately also decisive for the essentially force-fitting fastening of the valve housing 1 in the valve receptacle body 2.
  • the circumferential annular grooves prove to be a constructively useful measure Recesses 3 on the valve housing 1, which are arranged approximately in the form of a groove, each on the lateral surface of the valve housing 1 which is graduated in diameter.
  • valve housing 1 - due to its decreasing gradation in diameter in the joining direction - takes over the function of a caulking punch, to which the stepped bore of the valve receiving body 2 is adapted in diameter.
  • the original depth of the respective bore step in the valve receiving body 2 is dimensioned to be correspondingly smaller by the volume to be displaced into the recess 3 in the joining direction than the required caulking stroke of the caulking plunger or the valve housing 1.
  • the sleeve-shaped valve housing 1 receives the pressure medium passage bores 11, 12 to be controlled by the valve tappet 9, the magnetic core 8, the valve sleeve 10, the valve seat 13 and a plate filter 16.
  • a ring filter 17 is located on the outer circumference of the valve housing 1 at the level of the pressure medium passage bore 12, which opens into the pressure medium-carrying cavity 5.
  • the ring filter element 17 not only performs the function the filtering out of pressure medium contaminants, but is dimensioned in its outer diameter, in the function of a sealing element such that a seal by means of a radially extending sealing edge 14 is present between the stepped bore and the caulking point 4 located above the ring filter 17.
  • a further hollow space 6 which absorbs solid and dirt particles and which likewise prevents the penetration of solid particles into the hollow space 5 guiding the pressure medium in the direction of the pressure medium passage bore 11 via a sealing lip (sealing edge 14) running around the plate filter 6.
  • a step 15 is provided in steps around the valve housing 1, which is delimited by the caulking point 4, the wall of the valve receiving body 2 and the sealing lip (sealing edge 14) on the ring filter 17 or plate filter 16. Due to the selected shape of the sealing lip (sealing edge 14), even if a pressure medium penetrates from the liquid-filled cavity 5 into the further cavity 6 that receives the solid particles, escape and contamination of the pressure medium through-bores 11, 12 due to the kickback effect of the sealing edge 14 is excluded. Any pressure medium flowing into the cavity 6 receiving the abrasion particles supports the blocking effect of the sealing lip (sealing edge 14), so that at most a pressure equalization in front of and behind the sealing lip (sealing edge 14) can occur.
  • the secure sealing of the valve housing 1 in the valve receiving body 2 is ensured in each case by the caulking point 4 arranged above and below the pressure medium passage bore 12, so that, on the one hand, a short-circuit current and thus pressure compensation between the two pressure medium through holes 11, 12 is prevented with a closed valve tappet 9, on the other hand when the valve tappet 9 is open, the fluid under high pressure cannot penetrate in the direction of the upper caulking point 4 shown on the surface of the valve receiving body 2. Consequently, the caulking points 4 not only generate the holding force for fastening the solenoid valve in the valve receptacle body 2, but also decisively effect the sealing of the hydraulically actuated valve components in the valve receptacle body 2.
  • FIG. 2 shows in detail, deviating from FIG. 1, to form the cavity 6 receiving dirt particles, a groove or groove-shaped recess on the circumference of the valve housing 1, which is located above the ring filter 17 and the pressure medium bore 12.
  • the metallic seal between the valve housing 1 and the valve receiving body 2 is ensured by the flank of the recess for the cavity 6 which acts as a sealing edge 14.
  • the metallic sealing of the cavity 6 can also be done by lining up a plurality of sealing edges 14, with the advantage that a sealing edge 14 is followed in turn by a cavity 6 downstream as a dirt trap, which on the one hand achieves comparable advantages with regard to the sealing measure with a labyrinth seal, and on the other hand the multiplication the cavities 6 contribute to an increase in the particle volume uptake. This is illustrated by way of example in FIG. 2 in the area above the plate filter 16 by arranging redundant cavities 6 and sealing edges 14.
  • the invention makes it possible to caulk the valves in the valve receiving body 2 without contamination of to have to accept functionally relevant components, so that special flushing and cleaning processes of the hydraulic channels are eliminated.
  • valves by means of self-caulking, functional elements fastened in a housing, which are subject to particular internal cleanliness with regard to their accuracy of fit and design of the channels.
